3 Claims.

Thisinvention has to do with a display device for the' dispensing Vofbeverages and relates particularly to the parts thereof arranged forheat transfer.

It is an object of the present invention to provide a unique form ofbeverage cooling or heating apparatus having concentric spaced-apartwalls and from which the beverage may be conveniently dispensed.

Another object ofthe present invention is the provision of an improvedcooling (or heating) and dispensing apparatus having a cooling (orheating) element removably disposed Within the reservoir thereof andsuitable for agitating the contents of such reservoir.

Still another object of the present invention is the provision of anattractive apparatus for the cooling (or heating) of beverages and inwhich there is a cooling (or heating) element extending into the body ofthe beverage, there being agitating means on the cooling (or heating)element and means operatively connected to the cooling element andextending exteriorly of the apparatus for manually manipulating theagitating means.

Another object of the present invention is the provision of a cooling(or heating) device of the above type and which includes illuminatingmeans for displaying the beverage contained therein.

Another object of the invention is the provision of a device of theabove named character in which a heating element may be readilysubstituted for a cooling element without structural changes in thedevice.

With these and other desirable objects in view, the descriptionhereinafter given is set forth in connection with the accompanyingdrawing illustrative of one form of the invention and hereby made a partof this specication and in which:

Figure 1 is a front elevation of the invention showing a part in crosssection; x

Figure 2 is a plan view of the invention and taken from above; and yFigure 3 is a fragmentary vertical sectional View of the invention toillustrate a faucet installation thereof.

Like reference characters will be used in theV drawing and throughoutthe following description to indicate similar parts of the invention.Figures 1, 2 and 3 should be read conjointly with the description thatiollows.` Y

In the illustrated form, the device comprising the invention isgenerally cylindrical, the lower end thereofy resting upon a circularbase 10. An

inturned annular ilange 11 serves to support the device vertically whilelateral displacement of the device, from the base, is precluded by avertically disposed liange 12. Threaded apertures 13 and 14, antipodallyarranged in the base 10, are adapted to receive the lower ends -of bracerods 15 and 16. Brace rod 15 may be hollow whereby it may serve as aconduit for the accommodation of an electric .conductor cable 17.

Usually an end of the cable 17 will be led from the device by way of anaperture 18 in a side of base 10. Any standard form of electric plugmember 19 may be provided at the end of the cord conductor 17 for theattachment to an electric power source.

An outer cylindrical vessel 20 has vertical side walls 2l and a bottom22. The bottom 22 may be slightly arched, if desired, so that it cansafely withstand pressure caused by the weight of other parts of thedevice supported thereby. Vessel 20 is made of transparent material,preferably glass.

Arranged concentrically within the vessel 20 is a second and quitesimilarly constructed vessel 23 having side walls 24 and a bottom 25.'So

that an air space will be formed between the two vessels 20 and 23, thelatter named vessel is of a selected smaller diameter.

Formed within the center of the bottom 25 of vessel 23, which serves asa reservoir for the beverage to be cooled or heated, is a depressedportion 26 upon vwhich the vessel 23 is to rest. A cushioning member 27will usually be suitably secured between the depressed bearing portion26 and the bottom of vessel 20. Member 27v may be made of hard rubber.The walls 21 and 24 of the vessels are conterminant in elevation tobetter adapt a cover member 28 to t thereupon. Cover member 28 willusually be made by casting or pressing metal into the desired shape.However, the cover 28 may be made of glass or other transparent materialso that it will permit the passage of light, from an incandescent bulb29, downwardly into the beverage Within the vessel 23.

Circumscribing the under side of the cover 28 Vare two ilanges 30 and 31that serve to effect a groove 32. In the upper face of the cover is acircular groove 33, which coincides with and eX- tends downwardly intothe body of ilange 31.

Within the-center of the cover 28 is a relatively large opening 34, fromwhich one or more slits 35 may extend. Two annular strips of softrubber, or the like, 36 and 37, will generally be secured to the bottomof the cover'28 by means of an adhesive. V,When the cover is placed overthe two vessels 20 and 23 the tops of walls 21 and 24 will coincide withthe pads 36 and 37, respectively, and fit snugly to the sides of flanges30 and 31 so that the cover will fit tightly in place and not be subjectto lateral movement. Apertured ears 38, within the cover 28, receive theupper ends of rods 15 and 16. Threaded heads 39 and 40 engage the upperends of rods 15 and 16 and screw down onto said ears to hold the coverfirmly seated upon the top of vessels 2O and 23.

It is desirable that the threaded head 39 be hollow as shown so that theelectric conductor cable 17 may be led outwardly therefrom toa lightsocket 4l for the bulb 29. If desired, the socket 41 may be pivotallyattached to the cover 28 as by means of a bracket 42 so that the bulb 29may be easily displaced from its position over the cylindrical member43.

After the cover 28 has been placed upon the device in the mannerdescribed, the cooling member 43 may be assembled with the device byinserting it through opening 34 and into the vessel 23. The member 43 iscylindrical and constructed from metal or other heat conductingmaterial. Member 43 is hollow to adapt it to hold ice or solidifiedcarbon dioxide or other cooling agent, or, if member 43 is to heat thecontents of vessel 23, said member may have heating means therein suchas a resistance coil. At the bottom of member 43 there may be placed aspindle 44 for being journaled in the depressed section 26 of the innervessel. In Figure 1 is shown a nn 45 as attached to the side of cooling(or heating) member 43; more of such fins may be provided if desired.rIhe n, or ns, may be hollow and open to the cylinder 43 to furtherspread its effect. If more ns are placed upon the wall of the coolingmember, they may be staggered with respect to a horizontal sectionthrough the member. For each fin provided in the device there must be aslit 35 in the cover 28 to permit the passage of such fins through thecover as the member 43 is lowered into the device.

A cover (not shown) may be used for fitting over the upper end ofcylindrical member 43, if and when desired.

Extending radially from the top of the cylindrical member 43 is a handle46. Said handle projects far enough beyond the peripheral edge of thecover that it may be easily grasped by an attendant for manipulating tooscillate the member 43 upon its bearing spindle 44 and to thereby movethe fin or ns 45 within the beverage being treated.

For covering the top of the device is a domeshaped piece 47, which restsupon the cover mem ber 28. About the lower edge of the dome-like piece47 is a flange 48 for seating in the circular recess 33 to insure theproper and secure seating of the piece. A section 49, for a distance offortyflve degrees with respect to the spherical center of the dome 47,lis removed from the lower edge of the dome to accommodate angularmovement of the handle 46. Section 49 also provides a convenient passagefor cable 17 into the dome. An opening 49a in the top of the dome coactswith the section 49 to create a current of air for conducting heat,generated in the light bulb 29, from the dome.

The contents of the vessel, which may be placed therein by way ofopening 34 when the member 43 is removed, may be drawn from the devicethrough a faucet 50, which is placed at a lower side of the device.Holes 51 and 52 in the vessel walls 21 and 24, respectively, are drilledlarger than the outside diameter of the hollow stem 53 of faucet 50.Gaskets of cork, rubber, or other suitable material indicated bynumerals 54, 55 and 56, engage the opposite sides of the walls traversedby the faucet stem to prevent leakage of the liquid contents of thedevice and to provide a cushioned mounting for the faucet so that noinjury may occur to the glass walls of the vessels by contact with ametal faucet. A nut 57 screws onto the inner end of the faucet stem andcoacts with the faucet shoulder 58 to compress the gasket members andwalls of the vessels tightly together. By manipulating the handle 59 theplug 60 can be turned to adjust the faucet so that a liquid may passtherethrough from the device.

Because of the double wall structure of the present cooling or heatingand dispensing unit,the dissipation of cooling or heating energy isgreatly reduced. Cover plate 28, whether transparent to provide forlight passing therethrough from the light source 29, or opaque, coactswith the spaced-apart walls to form a dead air space about thereservoir.

Other advantages of the device reside in the disposition andconstruction of the cylinder 43, containing the cooling or heatingagent, it having quite thin heat conductive walls so that there can be arapid transfer of heat between the cylinder and the beverage in which itmay be immersed. The rate of transfer of heat energy between thebeverage and the cylinder member 43 may be further increased by movingthe handle 46 to oscillate the member and hence to move the fins 45 toturbulate the beverage.
